Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_bluetooth.so

[montgoss]

After pairing bluetooth headphones, an attempt to play sound generates the following error:
ALSA lib pcm.c:2106:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_bluetooth.so
aplay: main:546: audio open error: No such file or directory

My asound.conf contains:
pcm.!default {

type bluetooth
device "00:1A:45:1C:58:DE"

}
ctl.!default {

type bluetooth

}
pcm.bluetooth {

type bluetooth

}
ctl.bluetooth {

type bluetooth

}
# default dmix configuration
pcm.plug {

type plug
slave.pcm "dmix"

}
ctl.mixer0 {

type hw
card 0

}

is the above mentioned library installed at all?

Exactly which library? alsa-lib 1.0.15-r0 is installed. I also installed kernel-module-snd-pcm. Made no difference.

[zecke]

Well the summary says "Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_bluetooth.so". Is that file present?

Nope. The only thing in the alsa-lib folder is a "smixer" folder.

Okay, from where did you get the asound.conf example? We have to make sure that we update the information... I think you will need to install bluez-utils-alsa.... but we might need to update the documentation?

From the wiki of course: ​http://wiki.openmoko.org/wiki/Manually_using_Bluetooth#A2DP

And I don't see a bluez-utils-alsa. Where can I get that? It doesn't appear to be in the repository.

If/when you get this working, please see ticket #1656 and add a comment saying if you can reproduce the symptoms. I'm interested in seeing if other people can hear A2DP fine or not with a freerunner.

The documentation tells you to install bluez-utils-alsa, you didn't install it and alsa complains about a missing library that is provided by bluez-utils-alsa.

The bluez-utils-alsa package should show up in the ASU feed soon, for the other builds it is not in my control and feel free to file a separate bug.

I have also tried this I am running into an issue with signatures. The instructions are fodder of they do not work. I know there is a closed ticket saying that this has been fixed. But where? How? It simply says OM2008.8. Must I use an unstable version for this to work?

[shashaness]

I do not know why this was closed.

I have the same issue. I followed the instruction on the wiki with both the original release of qTopia and 2007 (the latest builds) and it still does not work.

The required library is not there, obviously because of a missing package we need. I would love to test this, if I can get the package I need to make it work.

[zecke]

The reason I closed this bug is. The summary says a library can not be found, we identified that the library is not on the system (this explains why it can not be opened), we saw that the instructions do mention the installation of a package and this explains why the library is not present. If one is following the instructions (like installing a package) the setup is not going to fail at that point.

For OM2008.8 bluez-utils-alsa is in the feed and with my initial closing of the bug I encouraged to file separate bugs if the package is not available in the feed of your favored flavor (2007.2, FSO...).

Not to add fuel to the fire, but I did open a bug shortly after you closed this ticket. See #1683. You'll see that that bug was closed saying the package is available in Om2008.8, even though the summary specifically states that it's missing from the OM2007.2 repository.

Arne Anka was kinda enough to host an ipkg on his site: ​http://www.ginguppin.de/node/22
You can also build this yourself if you have MokoMakefile? working. I believe the command to run is:
make build-package-bluez-utils-alsa

Oh, and here's a link to the Om2008.8 repository which contains the needed ipk:

Only use that if you have a OM2008.8 image on your device as well. Please do not mix images and feeds as this is asking for problems.

Sorry. Guess I was confused since the resolution was that it existed in the Om2008.8 repository. :-P ;-)
